You don't have the 'production' version of the CPU service manual with the microcode source do you? I only have the pre-release one which says that's to come later :-( Actually, do you mean P854 here? The P854 panel is a keypad with a pair of vacuum fluorescent displays (address and data) controlled by a 8048. The CPU was built from AMD 2900 series chips and included a memory management unit. I've never heard of one with core either. -tony (Who has a P850, P851 and P854 along with manuals and some spare boards)
